The powerup failure and the six consecutive beeps including the
permanently lit up environmental amber LED have all disappeared and the
server is now happy to come up and get to the console level.
It turned out that the 6 beeps mean "memory error (or bad checksum)
detected" and the remedy was to reseat the pair of DIMM memory modules
which I now have moved from bank 0 to bank 1...
This problem of mine wouldn't have been fixed without the great and
fabulous support and help of so many members of this fantastic Tru64
list...and I would like to personally give big thanks to:
Howard Arnold
Dr Thomas Blinn
Kris Smith
Iain Barker
Phil Sullivan
Martin Roende Andersen
Regards,
Alen
